In his 1913 manifesto The Art of Noise, Luigi Russolo had some bold futuristic thoughts about the role of noise in musical composition:
Noise accompanies every manifestation of life. Noise is familiar to us. Noise has the power to bring us back to life.
We must break at all costs from this restrictive circle of pure sounds and conquer the infinite variety of noise-sounds.
We must replace the limited variety of timbres and orchestral instruments by the infinite variety of timbres of noises obtained through special mechanisms.
I doubt if even Russolo himself could have envisioned the endless variety of electronic noise-sounds that are now possible in modern music.
In only a few of the following selections is noise the focal point and they speak for themselves. In most selections, however, the element of noise is more of a background theme rather than the center of attention. Here the noise-sounds are woven into the fabric of the music in such a way as to add interesting textures of sound ranging from delicate to robust and, thereby, giving the music a highly emotional quality. Modern electronic music has definitely went beyond Russolo. Russolo would be proud.
